Editing area must scroll left / right to see all contents on php pages

can you somehow fix this “bug” that happens whenever a page has html or a php extension?

The edit view of the page extends past the boundaries and the user must scroll left/right to see all of the contents.

This only happens on a stacks page that has some kind of html or php added such as a markdown stack or a paysnap type of stack that forces the page to turn to .php extension.

Is there a way to fix/prevent this from happening?

edit This seems to happen with some html and markdown stacks as well. anyone have any solution?
